Patricia Clarkson, Bruno Ganz, Kristin Scott Thomas, Emily Mortimer, Cillian Murphy, Timothy Spall and Cherry Jones are to star in Sally Potter’s film “The Party,” which has just started its 14-day shoot in London.

Set in a house in contemporary London, the film is “a comedy wrapped around a tragedy,” according to Potter’s production company Adventure Pictures. “It starts as a celebration and ends with blood on the floor.”

The film is produced by Christopher Sheppard for Adventure Pictures and Kurban Kassam (“20,000 Days on Earth,” “Ginger & Rosa”), and is financed by Robert Halmi Jr. and Jim Reeve’s Great Point Media. ICM Partners is representing North American rights on the film, and the agency also represents Potter.

It is the eighth feature film to be directed by Potter, who is best known for “Orlando,” the 1992 adaptation of Virginia Woolf’s novel. The film, which starred Tilda Swinton, received two Academy Award nominations. Her other films include the BAFTA-nominated “The Tango Lesson” (1996); “Yes” (2004), with Joan Allen, Simon Abkarian, and Sam Neill; “The Man Who Cried” (2000), starring Christina Ricci, Johnny Depp, Cate Blanchett and John Turturro; “Rage” (2009), with Jude Law, Judi Dench and Steve Buscemi; and “Ginger & Rosa” (2012), starring Elle Fanning and Alice Englert.
